Electrical and magneto-transport in the 2D semiconducting MXene Ti₂CO₂

Abstract

The Hall scattering factor is formulated using Rode’s iterative approach to solv- ing the Boltzmann transport equation in such a way that it may be easily computed within the scope...

Can magnetotransport properties provide insight into the functional groups in semiconducting MXenes?

“…5, we show the calculated Hall factor for all the three compounds, Sc 2 CF 2 , Sc 2 CO 2 and Sc 2 C(OH) 2 both as a function of temperature and electron concentration. It is important to note here that Hall factor formulated by us 35 as shown in eqn (17) depends on both the perturbations g(ε) as well as h(ε). Such a method is quite distinct in comparison to the similar currently proposed method, for example, the one adopted by Macheda et al, 33 where the authors have calculated the Hall scattering factor in graphene in terms of the solution of the Boltzmann transport equation.…”

“…Studies on magnetotransport of materials using first principles are very scarce. Macheda et al investigated magnetotransport in diamond, 33 and graphene, 34 and our recent work on Ti 2 CO 2 35 are the few existing reports. Also, the transverse magnetoresistance of copper, bismuth and WP 2 are determined by combining ab initio Fermi surfaces with Boltzmann transport theory by Zhang et al 36 Magnetotransport in semiconductors was used primarily to quantify carrier concentration, which facilitates the design and production of efficient electronic devices.…”

“…We have already discussed three scattering mechanisms: scattering due to acoustic phonons, piezoelectric scattering, and scattering due to polar optical phonons in Ref. 35 and how to determine the scattering rates are provided in detail.…”

Advancing carrier transport models for InAs/GaSb type-II superlattice MWIR photodetectors

“…where, µ H and µ are the Hall and the drift mobility, respectively, and r H is the Hall scattering factor. This solution gives a more accurate result for the Hall scattering factor compared with the other expressions based on the RTA [71].…”

“…Similarly, in the presence of an arbitrary magnetic field, the BTE can be solved. The distribution function in such cases can be written as [33,71]…”
